Alkyl glycosides were synthesised from starch and alcohols using Aspergillus oryzae a-amylase as catalyst. In the degradation of starch by a-amylase, the alcohols competed with water as glycosyl acceptors. In the reaction with methanol, methyl maltoside and methyl maltotrioside were the main alcoholysis products. Conversion of 45 g/1 starch in 30% methanol resulted in a product mixture containing

UV-B treatment of thylakoid membranes or fractions derived from them accelerates the first rise (Fo---Fi phase) of variable fluorescence and slows down the second (Fi---Fm) rise. This can be observed for all membrane fractions but to different extents. The grana fraction is affected more by the UV-B treatment than are the intact thylakoids and the stroma lamella fraction. An exogenous electron acc

A search for events containing an isolated electron or muon and missing trans verse momentum produced in e(+/-)p collisions is performed with the H1 and ZEUS detectors at HERA. The data were taken in the period 1994-2007 and correspond to an integrated luminosity of 0.98 fb(-1). The observed event yields are in good overall agreement with the Standard Model prediction, which is dominated by single

In this study stool samples from dyspeptic patients and healthy subjects were used for detection of specific Helicobacter pylori antigens and DNA by immunoenzymatic test (PPHpSA) and semi-nested PCR (ureA-PCR), respectively. The H. pylori status was estimated by invasive endoscopy-based rapid urease test and histology or noninvasive urea breath test (UBT), and by serology (ELISA, Western blot). Th

Calculated absorbed dose distributions from tangential irradiation of the breast have been compared with TLD measurements in a anthropomorfic body-shaped phantom which has gone through all phases of the radiation treatment planning cycle, including mapping of electron densities with a CT scanner, simulation of beam set-up and several treatments with an accelerator. The absorbed doses, measured in

The ATP- and UTP-sensitive P2Y2 receptor which mediates both contractile and mitogenic effects has recently been shown to be upregulated in the synthetic phenotype of the vascular smooth muscle cell (VSMC). Using a competitive RT-PCR we demonstrate that the P2Y2 receptor mRNA is increased by fetal calf serum and other growth factors in a MAPKK-dependent way. This was confirmed at the functional le

A technology was developed to embed nm-sized metallic features in close vicinity to semiconductor heterostructures, which allows a direct integration of resonant tunneling diodes (RTD) inside the channel of permeable base transistor. A AlGaAs/InGaAs based RTD was grown by molecular beam epitaxy (MBE), with peak current density either 70 or 120 kA/cm². A fundamental oscillation frequency

Natural lifetimes of some highly excited levels in the Pb-I spectrum have been measured by the zero field level crossing (Hanle) method. The levels were reached by optical excitation from the metastable 6p2 3P2 and 6p2 3P1 states, were a considerable population had been created by means of adc discharge in a Pb atomic beam. An atomic beam source producing atoms in metastable states is described. F

Purpose: The creation of brand and brand identity has been discussed widely among scholars. However, the literature about what causes a brand to lose its identity is rarely tackled. Therefore, this research serves as a preliminary examination by looking into the causes and actions undertaken by organisations that are negatively projected on the brand identity. Methodology: Secondary data analysi

Purpose: This article explores the relation between brands and the use of art, and in which way art helps brands in expressing their values and identity. Furthermore, this article will identify the components that characterize Artistic Brands and Brands with Art. Design/Method/Approach: A qualitative approach will be used, and data will be drawn from six different case studies of brands collaborat

Electric cars are by many considered a sustainable solution to the ever-growing demand for road vehicles and fuel. The transportation sector is responsible for almost a third of the total greenhouse gas emissions globally and approximately 80% of these emissions can be attributed to road vehicles. Thus, there is an urgent need for a shift away from fossil fuels in the sector. While the consumer in

Prominent research of creativity and affect has historically illuminated the relationship between positive affect and creativity, whereas little is known about the effects- influence of negative affect on creativity. The present study aimed to investigate how negative affect influenced creativity by using a divergent and convergent creativity task. A sample of 54 participants was recruited and ran

Politics should be constituted by social representativeness in order to be conceptualised as democratic and legitimate. The set of politicians ought to be diverse and heterogeneous with the aim to include a wide spectrum of interest and concerns. The debate about women lacking power in politics was raised in the seventies. The political parties acted in response to the debate by implementing diffe
